EUSTORGIO, saint. — He is said to have been bishop of Milan between 343 and 350. He is praised by St. Atanasio and St. Ambrogio as a zealous and fervent orthodox Christian; unfortunately, however, no other reliable information is known. There is a biography written by Landolfo in the 11th century, according to which E. was sent from the East as governor of Milan. At the death of Protasio he was acclaimed bishop, but he would not accept the dignity without the Emperor’s assent and approval. He therefore went to Constantinople, from where he returned with privileges for the city and bearing the bodies of the holy Magi. During his episcopate, the two synods against Fotino were held at Milan, in 346 and 348. He is commemorated on 18 September.
